Therefore, the purpose of this study is to determine the effects of 12 weeks of omega-3 supplementation at 3 g/day on metabolic and physical health parameters in community-dwelling older adults. We hypothesize that EPA and DHA supplementation will result in 1) a decrease in resting heart rate and blood pressure; 2) a more healthy blood profile; 3) an increase in resting metabolic rate; 4) a greater reliance on fat oxidation for energy both at rest and during exercise; and 5) a decrease in fat mass; and 6) an increase in lean mass, strength and physical function.
